Dear Mr. President,

    I am writing this letter to say something about the food in our university’s canteen.

Firstly, the quality of the dishes should be improved. Undoubtedly, there are a lot of delicious dishes, but all the year round, they are the same. More and more students are complaining about eating the same food each day. So I think the most urgent problem is variety.

    Secondly, the price is a bit too high. Many of us hope that the canteen can provide us with not only delicious but also cheaper food.

    Finally, the environment is so noisy that we can’t enjoy our meals in good mood. I suggest that there be some soft music to help us relax.

    These suggestions are not just of my own, but also of may other students. We hope our respectable president will pay attention to our suggestions.

    By the way, the canteen workers are very patient and always smiling. So I think if our university offers them better conditions, they will offer us better service.

                                                                   Best wishes,

                                                                     Li Ming

Dear Xiao Wang,

　　 I'm delighted to learn that you are going to visit me during the week-long holiday. My parents will also be happy to see you again. I'm sure you will enjoy every minute here.

　　 I know you are eager to go sightseeing along the Westlake. So I’ll show you around in the morning. I think it would be very pleasant and refreshing to take a walk in such a beautiful scenic spot. In the afternoon, we can pay a visit to the campus of Zhejiang University, whose atmosphere is just what you are dreaming for, I think. Besides, a mountain behind Zhejiang University is very beautiful and it is also worthy of touring. When we climb to the top of the mountain, we can have a wonderful bird-eye view of the whole city.

　　 Just phone me before you set off. There is no need for you to take anything. I'll prepare everything for you.

　　 I look forward to seeing you soon.   

                                                                     Yours,

　　                                                               Li Ming
